Re: [ptp-user] How to supply host list with "Generic MPICH2 Interactive" target configuration ?
I suspect that debugging mvapich2 apps does not work the same way as mpich2. Take a look at ~/.eclipsesettings/rms/MPICH2/start_debug_job.pl and see if you can see how the debugger is launched. You'll need to work out if the same process can be used for mvapich2.

If you have a modified target configuration and/or scripts for mvapich2, I'd be happy to include them in the next release of PTP.

Regards,
Greg

Hi Greg and first of all, thank you for your feedback !

To give you further details, i'm trying to use Eclipse PTP (Neon) as a development/debugging platform for use with MVAPICH2 2.2.

Thanks to your previous instructions (with some little differences as MVAPICH2 recommends to use mpirun_sh command instead of mpiexec, which has a slightly different syntax), i finally have my jobs correctly running on the specified hosts and everything seems to work fine.

I'm now trying to debug the HelloWorld sample application with 2 jobs to debug on my local host and I get the following error in the console output:

#PTP job_id=2593
[joel:mpirun_rsh][signal_processor] Caught signal 2, killing job

Then, I have to cancel the launch as the "Progress information" dialog never ends. Finally, i get an error dialog with the message:

Error completing debug job launch

Reason:
Cannot connect to debugger

Have you any idea about this issue ?

Thank you for your help !

It looks like a bug. Are you familiar with how to edit target system configurations? If not, see this FAQ [1].

When you have the XML file in your workspace, find the following line:

<submit-interactive name="submit-interactive" directory="${ptp_rm:directory#value}" waitForId="true" keepOpen="true">

Now add the following four lines just before the line <arg>-np</arg>

<arg attribute="useHostFile" isUndefinedIfMatches="false">-hostfile</arg>
<arg attribute="useHostFile" isUndefinedIfMatches="false">${ptp_rm:host_file#value}</arg>
<arg attribute="useHostList" isUndefinedIfMatches="false">-host</arg>
<arg attribute="useHostList" isUndefinedIfMatches="false">${ptp_rm:host_list#value}</arg>

Save the file and try creating a new run configuration using the modified target configuration. Let me know if it works.

Regards,
Greg

Hello,

First of all, thank you for this powerful tool !

Apparently, neither the "host file" option nor the "host list" one seems to be supplied to the mpiexec command...

Is this a bug ? If it isn't, how can i supply a host list for the execution with the "Generic MPICH2 Interactive" target ?

Thanks !
